Amaterasu zarrachasi
Yapon mifologiyasidagi quyosh ma'budi sharafiga nomlangan Amaterasu zarrachasi 2021-yilda aniqlangan va keyinchalik 2023-yilda tavsiflangan O'ta yuqori energiyali kosmik nurlar o'ta yuqori energiyali kosmik nurdir [1]. U AQShning Yuta shtatidagi Telescope Array loyihasi Telescope Array Project rasadxonasi yordamida qayd etilgan. Uning energiyasi 240 eksa-elektronvoltdan (EeV) oshgan va u yer usti detektorlariga yuborgan o'nlab zarrachalar orqali aniqlangan. Ushbu yagona zarracha tushunarsiz tarzda Somon yoʻli galaktikasi bilan chegaradosh bo'shliq — Mahalliy bo'shliqdan (Local Void) kelib chiqqan ko'rinadi.[2] Ushbu subatom zarracha taxminan bel balandligidan yerga tushayotgan g'ishtning energiyasiga teng energiyaga ega edi.[3]
Tadqiqot rahbari, Osaka Metropolitan universiteti dotsenti Toshihiro Fujiining so'zlariga ko'ra, "Kosmik nur kelgan yo'nalishga mos keladigan hech qanday istiqbolli astronomik ob'ekt aniqlanmadi, bu esa noma'lum astronomik hodisalar va Standart modeldan tashqari yangi fizik kelib chiqish ehtimolini ko'rsatadi."[4] Keyinchalik 2026-yilda o'tkazilgan tadqiqot zarrachalar ehtimol NGC 6946, Messier 82 yoki NGC 2403 dan kelib chiqqanligini taxmin qildi.[5]
Ilgari xabar qilingan o'ta yuqori energiyali kosmik nur hodisalariga 1991-yildagi 320 EeV quvvatli zarracha[6] (Oh-My-God zarrachasi), 1993-yildagi 213 EeV quvvatli zarracha[7][1] va 2001-yildagi 280 EeV quvvatli zarracha kiradi.[8] Bu Amaterasu zarrachasini hozirgacha aniqlangan uchinchi eng kuchli kosmik nurga aylantiradi.
